uneven divider

Hi
I'm designing three way uneven wilkinson power divider for three stage Doherty Power Amplifier. I need some examples about the ratios that use in the three stage Doherty amplifier to design the Power Divider.

Thanxxxxx for help

General Design Equations of N-Way Arbitrary Power Dividers

Thanx burton for your help, but I know how to design N way Wilkinson Power Divider and I have already designed this power divider, my problem is that I need ratio values that use for uneven power drive multistage doherty amplifier e.g. the ratio that use in 3 stage doherty amplifier and I need to know why this ratio used for this amplifier.

thanxx in advance....

You don't need a divider but a coupler. Depending on the coupling factor more or less power is split off the main line.
